Steps to Calculate GCD of 155, 985, 457, 707 using LCM Formula
Given numbers are 155, 985, 457, 707
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 985) = 30535
GCD(155, 985) = ( 155 x 985 ) / 30535
= 155 / 985
= 155
Step2:
LCM(5, 457) = 2285
GCD(5, 457) = ( 5 x 457 ) / 2285
= 5 / 457
= 5
Step3:
LCM(1, 707) = 707
GCD(1, 707) = ( 1 x 707 ) / 707
= 1 / 707
= 1
So, Greatest Common Divisor of 155, 985, 457, 707 is 1
