Given numbers are 139, 646, 151, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(139, 646) = 89794
GCD(139, 646) = ( 139 x 646 ) / 89794
= 139 / 646
= 139
Step2:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
Step3:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
So, Greatest Common Divisor of 139, 646, 151, 491 is 1
