Given numbers are 708, 642, 257, 572
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(708, 642) = 75756
GCD(708, 642) = ( 708 x 642 ) / 75756
= 708 / 642
= 708
Step2:
LCM(6, 257) = 1542
GCD(6, 257) = ( 6 x 257 ) / 1542
= 6 / 257
= 6
Step3:
LCM(1, 572) = 572
GCD(1, 572) = ( 1 x 572 ) / 572
= 1 / 572
= 1
So, Greatest Common Divisor of 708, 642, 257, 572 is 1
