Given numbers are 786, 196, 693, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 196) = 77028
GCD(786, 196) = ( 786 x 196 ) / 77028
= 786 / 196
= 786
Step2:
LCM(2, 693) = 1386
GCD(2, 693) = ( 2 x 693 ) / 1386
= 2 / 693
= 2
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 786, 196, 693, 780 is 1
