Given numbers are 770, 188, 671, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 188) = 72380
GCD(770, 188) = ( 770 x 188 ) / 72380
= 770 / 188
= 770
Step2:
LCM(2, 671) = 1342
GCD(2, 671) = ( 2 x 671 ) / 1342
= 2 / 671
= 2
Step3:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
So, Greatest Common Divisor of 770, 188, 671, 657 is 1
