Given numbers are 778, 971, 642, 237
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 971) = 755438
GCD(778, 971) = ( 778 x 971 ) / 755438
= 778 / 971
= 778
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 237) = 237
GCD(1, 237) = ( 1 x 237 ) / 237
= 1 / 237
= 1
So, Greatest Common Divisor of 778, 971, 642, 237 is 1
