Given numbers are 670, 715, 686, 836
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 715) = 95810
GCD(670, 715) = ( 670 x 715 ) / 95810
= 670 / 715
= 670
Step2:
LCM(5, 686) = 3430
GCD(5, 686) = ( 5 x 686 ) / 3430
= 5 / 686
= 5
Step3:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
So, Greatest Common Divisor of 670, 715, 686, 836 is 1
