Given numbers are 642, 647, 804, 625
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 647) = 415374
GCD(642, 647) = ( 642 x 647 ) / 415374
= 642 / 647
= 642
Step2:
LCM(1, 804) = 804
GCD(1, 804) = ( 1 x 804 ) / 804
= 1 / 804
= 1
Step3:
LCM(1, 625) = 625
GCD(1, 625) = ( 1 x 625 ) / 625
= 1 / 625
= 1
So, Greatest Common Divisor of 642, 647, 804, 625 is 1
