Given numbers are 778, 392, 171, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 392) = 152488
GCD(778, 392) = ( 778 x 392 ) / 152488
= 778 / 392
= 778
Step2:
LCM(2, 171) = 342
GCD(2, 171) = ( 2 x 171 ) / 342
= 2 / 171
= 2
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 778, 392, 171, 770 is 1
