Given numbers are 132, 688, 390, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(132, 688) = 22704
GCD(132, 688) = ( 132 x 688 ) / 22704
= 132 / 688
= 132
Step2:
LCM(4, 390) = 780
GCD(4, 390) = ( 4 x 390 ) / 780
= 4 / 390
= 4
Step3:
LCM(2, 641) = 1282
GCD(2, 641) = ( 2 x 641 ) / 1282
= 2 / 641
= 2
So, Greatest Common Divisor of 132, 688, 390, 641 is 1
