Steps to Calculate GCD of 915, 842, 455, 557 using LCM Formula

Given numbers are 915, 842, 455, 557

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(915, 842) = 770430

GCD(915, 842) = ( 915 x 842 ) / 770430

= 915 / 842

= 915


Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1


Step3:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1


So, Greatest Common Divisor of 915, 842, 455, 557 is 1
