GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(488, 820) = 100040
GCD(488, 820) = ( 488 x 820 ) / 100040
= 488 / 820
= 488
Step2:
LCM(4, 117) = 468
GCD(4, 117) = ( 4 x 117 ) / 468
= 4 / 117
= 4
Step3:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
So, Greatest Common Divisor of 488, 820, 117, 771 is 1
