GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 790) = 248060
GCD(628, 790) = ( 628 x 790 ) / 248060
= 628 / 790
= 628
Step2:
LCM(2, 781) = 1562
GCD(2, 781) = ( 2 x 781 ) / 1562
= 2 / 781
= 2
Step3:
LCM(1, 963) = 963
GCD(1, 963) = ( 1 x 963 ) / 963
= 1 / 963
= 1
So, Greatest Common Divisor of 628, 790, 781, 963 is 1
