Given numbers are 680, 692, 707, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 692) = 117640
GCD(680, 692) = ( 680 x 692 ) / 117640
= 680 / 692
= 680
Step2:
LCM(4, 707) = 2828
GCD(4, 707) = ( 4 x 707 ) / 2828
= 4 / 707
= 4
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 680, 692, 707, 630 is 1
