Given numbers are 647, 643, 762, 488
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 643) = 416021
GCD(647, 643) = ( 647 x 643 ) / 416021
= 647 / 643
= 647
Step2:
LCM(1, 762) = 762
GCD(1, 762) = ( 1 x 762 ) / 762
= 1 / 762
= 1
Step3:
LCM(1, 488) = 488
GCD(1, 488) = ( 1 x 488 ) / 488
= 1 / 488
= 1
So, Greatest Common Divisor of 647, 643, 762, 488 is 1
