GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 534) = 38982
GCD(438, 534) = ( 438 x 534 ) / 38982
= 438 / 534
= 438
Step2:
LCM(6, 869) = 5214
GCD(6, 869) = ( 6 x 869 ) / 5214
= 6 / 869
= 6
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 438, 534, 869, 720 is 1
