Given numbers are 423, 242, 660, 772
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 242) = 102366
GCD(423, 242) = ( 423 x 242 ) / 102366
= 423 / 242
= 423
Step2:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
Step3:
LCM(1, 772) = 772
GCD(1, 772) = ( 1 x 772 ) / 772
= 1 / 772
= 1
So, Greatest Common Divisor of 423, 242, 660, 772 is 1
