GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(716, 820) = 146780
GCD(716, 820) = ( 716 x 820 ) / 146780
= 716 / 820
= 716
Step2:
LCM(4, 646) = 1292
GCD(4, 646) = ( 4 x 646 ) / 1292
= 4 / 646
= 4
Step3:
LCM(2, 783) = 1566
GCD(2, 783) = ( 2 x 783 ) / 1566
= 2 / 783
= 2
So, Greatest Common Divisor of 716, 820, 646, 783 is 1
