Given numbers are 644, 504, 107, 102
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 504) = 11592
GCD(644, 504) = ( 644 x 504 ) / 11592
= 644 / 504
= 644
Step2:
LCM(28, 107) = 2996
GCD(28, 107) = ( 28 x 107 ) / 2996
= 28 / 107
= 28
Step3:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
So, Greatest Common Divisor of 644, 504, 107, 102 is 1
