Given numbers are 642, 714, 694, 543
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 714) = 76398
GCD(642, 714) = ( 642 x 714 ) / 76398
= 642 / 714
= 642
Step2:
LCM(6, 694) = 2082
GCD(6, 694) = ( 6 x 694 ) / 2082
= 6 / 694
= 6
Step3:
LCM(2, 543) = 1086
GCD(2, 543) = ( 2 x 543 ) / 1086
= 2 / 543
= 2
So, Greatest Common Divisor of 642, 714, 694, 543 is 1
