Given numbers are 715, 390, 251, 934
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(715, 390) = 4290
GCD(715, 390) = ( 715 x 390 ) / 4290
= 715 / 390
= 715
Step2:
LCM(65, 251) = 16315
GCD(65, 251) = ( 65 x 251 ) / 16315
= 65 / 251
= 65
Step3:
LCM(1, 934) = 934
GCD(1, 934) = ( 1 x 934 ) / 934
= 1 / 934
= 1
So, Greatest Common Divisor of 715, 390, 251, 934 is 1
