Given numbers are 438, 252, 751, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 252) = 18396
GCD(438, 252) = ( 438 x 252 ) / 18396
= 438 / 252
= 438
Step2:
LCM(6, 751) = 4506
GCD(6, 751) = ( 6 x 751 ) / 4506
= 6 / 751
= 6
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 438, 252, 751, 621 is 1
