Given numbers are 105, 414, 70, 656
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 414) = 14490
GCD(105, 414) = ( 105 x 414 ) / 14490
= 105 / 414
= 105
Step2:
LCM(3, 70) = 210
GCD(3, 70) = ( 3 x 70 ) / 210
= 3 / 70
= 3
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 105, 414, 70, 656 is 1
