Given numbers are 438, 451, 778, 650
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 451) = 197538
GCD(438, 451) = ( 438 x 451 ) / 197538
= 438 / 451
= 438
Step2:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
Step3:
LCM(1, 650) = 650
GCD(1, 650) = ( 1 x 650 ) / 650
= 1 / 650
= 1
So, Greatest Common Divisor of 438, 451, 778, 650 is 1
