The aim of this note is to investigate the products of element orders in finite groups and to give some properties
of such products. Let phi′(G) denote the product of element orders of a finite group G. As an immediate
consequence, by using a different approach, we proved that phi′(G) < phi'′(G) where G is a non-cyclic finite
group and C is a cyclic group of the same order.

Öz

Bu çalışmanın amacı sonlu grupların eleman mertebelerinin çarpımlarını araştırmak ve bu çarpımların bazı
özelliklerini vermektir. Bir sonlu grup G nin eleman mertebelerinin çarpımı phi′(G) olsun. Farklı bir yaklaşım
kullanarak aynı mertebeye sahip G devirli olmayan grup ve C devirli grup olmak üzere phi′(G) < phi′(C) olduğu
ispatlandı.

Anahtar Kelimeler

Sonlu grup, grup eleman mertebeleri, eleman mertebeleri çarpımı
