Given numbers are 639, 803, 612, 437
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 803) = 513117
GCD(639, 803) = ( 639 x 803 ) / 513117
= 639 / 803
= 639
Step2:
LCM(1, 612) = 612
GCD(1, 612) = ( 1 x 612 ) / 612
= 1 / 612
= 1
Step3:
LCM(1, 437) = 437
GCD(1, 437) = ( 1 x 437 ) / 437
= 1 / 437
= 1
So, Greatest Common Divisor of 639, 803, 612, 437 is 1
