Given numbers are 702, 780, 561, 136
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(702, 780) = 7020
GCD(702, 780) = ( 702 x 780 ) / 7020
= 702 / 780
= 702
Step2:
LCM(78, 561) = 14586
GCD(78, 561) = ( 78 x 561 ) / 14586
= 78 / 561
= 78
Step3:
LCM(3, 136) = 408
GCD(3, 136) = ( 3 x 136 ) / 408
= 3 / 136
= 3
So, Greatest Common Divisor of 702, 780, 561, 136 is 1
