Given numbers are 649, 532, 142, 947
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 532) = 345268
GCD(649, 532) = ( 649 x 532 ) / 345268
= 649 / 532
= 649
Step2:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
Step3:
LCM(1, 947) = 947
GCD(1, 947) = ( 1 x 947 ) / 947
= 1 / 947
= 1
So, Greatest Common Divisor of 649, 532, 142, 947 is 1
