Given numbers are 782, 632, 371, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 632) = 247112
GCD(782, 632) = ( 782 x 632 ) / 247112
= 782 / 632
= 782
Step2:
LCM(2, 371) = 742
GCD(2, 371) = ( 2 x 371 ) / 742
= 2 / 371
= 2
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 782, 632, 371, 644 is 1
