Given numbers are 420, 714, 131, 702
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 714) = 7140
GCD(420, 714) = ( 420 x 714 ) / 7140
= 420 / 714
= 420
Step2:
LCM(42, 131) = 5502
GCD(42, 131) = ( 42 x 131 ) / 5502
= 42 / 131
= 42
Step3:
LCM(1, 702) = 702
GCD(1, 702) = ( 1 x 702 ) / 702
= 1 / 702
= 1
So, Greatest Common Divisor of 420, 714, 131, 702 is 1
