Given numbers are 438, 964, 447, 764
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 964) = 211116
GCD(438, 964) = ( 438 x 964 ) / 211116
= 438 / 964
= 438
Step2:
LCM(2, 447) = 894
GCD(2, 447) = ( 2 x 447 ) / 894
= 2 / 447
= 2
Step3:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
So, Greatest Common Divisor of 438, 964, 447, 764 is 1
